SWITCH.

I Specification of Letters Patent.

Patented Feb. 17, 1920.

Application filed October 14,1919. Serial No. 330,619.

To all whom it may concern:

Be it known that I, SAMUEL H. Rosxn, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Switches, ofwhich the follfowing is a specification.

My invention relates to switches and the object is to provide an efficient switch and mechanism for operating same. The device isparticularly adaptable for use in street railways in cities where much switching is done and where it is necessary to have all switching mechanisms below the ground surface. The main object of the invention is to overcome what is known as jackdmifing. of switches where after one truck of a car has passed in onedirection the switch slips back and the rear truck will follow another track. Further objects will be disclosed in the course of the specification.-

.The invention is clearly illustrated in the accompanying drawings, in which:

Figure 1 is a top or plan view-of a portion of a street and railshaving a switch adapted to be operated by my device. I Fig. 2 is an enlarged detail View of the lower right hand portion of Fig. 1 .but with the box cover 9 removed.

Fig.3 is an enlarged detailed sectional view on the line 33 in Fig. 1. r 7

.Fig. 4 is a detailed view similar to Fig. 2 but withmany parts omitted for illustration purposes. 7 Q Y i Fig. 5 is an enlarged detailedsectional view on the line 5-5 in Fig. 3.

Fig. 6 is a detailed sectional view on the line v66in Fig. 4. I Fig. 7 is a bottom View of the switching plug 10. V n

Fig. 8 is a diametrical section on the line -88 in Fig. 7. r 7 r Referring to the drawings by reference numerals, 11 designates the main straight track having a flange groove 12, such as is ordinarily used in street railways. The secondary track 13 having a flange groove 14, that joins the main railll, and is operatively connected therewith by a wedgeshaped switch rail 15. Heretofore it has been customary to throw the switch rail 15 with a switch rod to the side desired, where it is only friction held until it is again switched. To overcome the objectionable features of the present type-of switch I providea mechanism which in particular is described as follows:

Adjacent the main rail 11 I provide a housing box 16, having a cover 9 substantially on the same level as the ground surface. A switching plug 10, which is provided with a slot 17 adapted to be engaged by a switching rod (not shown) is rotatably supported in a bracing plate 18 within the box, and extends through and slightly above the cover 9. The under side of said switching plug is provided with a substantially triangular recess 18 adapted to fit upon the top of the vertical actuating post 19 which is journaled at its bottom in a block 20, directly under the center of the switching plug 10.

Two parallel horizontal bars 21 are secured within the box 16, and slidably mounted thereon is a frame consisting of a primary yoke 22 and a secondary yoke 23 connected therewith by bolts 24. 1

Said bolts 24 are slidably mounted in the yoke 22, and about the same are two springs 26 which tend to hold the yokes in separated positions in so far as nuts 25 on said bolts will allow.

Secured by screws 27 to the yoke 22 is a latch or bolt element 28 provided with pins 29 slidably mounted in notches 30 (see Fig. 6) in projection 31 of the yoke 23. Said bolt 28 is provided with an aperture 32 (see Fig. 4) through which extends the actuating post 19, which upon being actuated shifts the bolt and yokes back and forth accordingly. An angular connecting rod 33 connects the yoke 23 to the under side of the switch rail 15. Thus when the switching plug 10 is rotated in the desired direction the post 19 shifts the frame and therefore also the switch rail 15 into the desired position. I

In order that the frame will snap into and be retained firmly in the desired position, I provide in connection with the actuating post 19 a device consisting of a rod 34 pivotally connected to an car 35 on said post, and slidably mounted with its other end in a bracket 36. A spring 37 about said rod pushes from the bracket 36 and tends to snap and hold into either position desired the ear 35 which of course swings only a quarter of a revolution about the post center.

To compensate for wear or other looseness of the post 19, within recess 32 of the bolt 28 I-provide a plate 37 adjustably secured by screws 38 to the bolt 28.

It is often found desirable to operate switches of this kind by electricity or some other means from a distance. For this purpose I provide an attachment as shown in Figs. 3 and 5. A lever arm 38 is pivotally secured at one end to a stud 39 on the bottom of the box 16; the other end being adapted to be actuated by a rod 40 extending from the secondary operating mechanism as within the box 41. An ear 42 integral to the actuating post 19 is connected by a link 43 to said lever arm 38.

In the operation of the device, the switch as shown is opened to the main track. It is impossible for the switch rail to move to the left because of sliding or vibration of the car passing thereover, because the yoke 23 cannot from any such cause move against the pressure of the springs 26. If, however a car is to move from the rail 13 on to the main rail 11 the wheel flanges will force the switch rail to the left against the pressure of the springs 26 which will thereafter again close the switch to the side track 11. If it is desired to move cars from the main rail on to the rail 13 the actuating post 19 is turned a quarter turn to the left (by either means described). This throws the entire frame and also the switch rail to the left where they are positively locked until again moved by the turning of the post 19 to the right.

Having now fully shown and described my invention what I claim to be new and desire to protect by Letters Patent is:

1. In combination with a railway switch having a switch rail adapted to be switched to either of two positions, of a box positioned adjacent said switch, a frame havinga recess therein. slidably mounted in said box and operatively connected to said switch rail, a switching post extending through said recess and being journaled at its ends in said box, means whereby turning of said switching post will shift said frame and switch rail back and forth, spring actuated means secured to said post whereby the same will be spring held in the position desired, and a lever arm pivotally mounted at one end within the box and-having its other end adapted to be connected to an operating mechanism, a link having one end pivotally connected to said lever arm and having its other end pivotally secured to an ear tension of said switching post.

2. In combination with a railway switch having a switch rail adapted to be switched to either of two positions, of a frame slidably mounted near and operatively connected to said switch rail, a switching post and operative connection whereby turning of the same will shift said frame and switch rail back and forth, means for yieldingly holding said post in the position desired, a

post and operative connection whereby 'turning of the same will shift said switch rail back and forth as desired, a lever arm pivotally mounted near and operatively con? nected to an ear, extension of said switching post, 'means for connecting said lever arm to an operating mechanism.

4. In combination with a railway switch having a switch rail adapted to be switched to either of two positions and a box positioned adjacent said switch, of a switching post ournaled at its ends in said box, operative connection whereby turning of said switching post will shift saidtswitch rail back and forth, and spring actuated means whereby said post will be yieldingly held in the position desired, a lever arm pivotally mounted at one end within the box and having its other end adapted to be connected to an operating mechanism, a link having one end pivotally connected to said lever arm and having. its other end pivotally secured to an ear extension of said switching post.

5. In combination with a railway switch having a switch rail adapted to be switched to either-of two positions and a box positioned adjacent said switch, of a switching post journaled at its ends in said box, operative connection whereby turning of said switching post will shift said switch rail back and forth, and spring actuated means whereby said post will be yieldin'gly held in the position desired, a lever arm pivotally mounted at one end within-the box and having its other end adapted to be connected to an operating mechanism, operative connection between said leverarm and said switching post.

6. In combination with a railway switch having a switch rail adapted to be switched to either of two positions, of a frame hav: ing a recess therein slidably mounted near and operatively connected to said switch rail, a switching post being substantially quadranta'l in cross section extending through a recess therein slidably mounted in said box and operatively connected to said switch rail, a switching post extending through said recess and journaled at its lower end in said box, a switching plug mounted to rotate in a hole in the top of said box, said plug having a recess in its bottom adapted to receive the upper end of said switching post, means whereby the turning of said switching post will switch said switch rail to either of the two positions desired.

8. In combination with a railway switch having a switch rail adapted to-be switched to either of two positions, of a frame having a recess therein slidably mounted near and operatively connected to said switch rail, a switching post extending through said recess and adapted to engage alternatively against opposite sides thereof whereby turning of said switching post will shift said frame and Switch rail back and forth, a plate adjustably secured to said frame and having one edge thereof forming one of said engaged sides of said recess, as and for the purpose set forth. 1

In testimony whereof I afiix my signature.
